We had an ultrasound at 13+2 and they gave us a prediction. During week 13 is when the genitals are becoming fully formed. I think our baby I was measuring a bit big. But they may be able to tell by 14 weeks. The best time is between 17-21 weeks though.
Awe bummer :'( well thank you!
14 weeks is early. They can be wrong that early. At 18 weeks, it should be accurate. They can tell by a genetic blood test early on. But that is not always covered by insurance and is expensive. It is actually meant for testing for things like down syndrome.
